Coal occupies a central position in modern human endeavors. Last year over 7000 megatons were mined worldwide. Powerful, yet dirty and dangerous, use of coal is expanding every year, with 2010 witnessing a production increase of 6.8%. Around 70 countries have recoverable reserves, which some estimates claim will last for over a hundred years at current production levels. Mining for coal is one of the world's most dangerous jobs. While deadliest in China, where thousands of miners die annually, the profession is still hazardous in the West and other regions as well. Our mining and use of coal accounts for a variety of environmental hazards, including the production of more CO2 than any other source. Other concerns include acid rain, groundwater contamination, respiratory issues, and the waste products which contain heavy metals. But our lives as lived today rely heavily on the combustible sedimentary rock. Over 40% of the world's electricity is generated by burning coal, more than from any other source. Chances are that a significant percentage of the electricity you're using to read this blog was generated by burning coal.

In the Jaintia hills, located in India's far northeast state of Meghalaya, miners descend to great depths on slippery, rickety wooden ladders. Children and adults squeeze into rat hole like tunnels in thousands of privately owned and unregulated mines, extracting coal with their hands or primitive tools and no safety equipment.

Okay, the title of this blog was meant to be sung to the Batman tune because, personally, I think the gray-garbed catbird appears much better suited to be Batman’s sidekick than the orange-breasted robin. But hey, even though this capped crusader failed to become a comic book icon, he does have the honor of being…
